------------------------------------

Thank you very much. HIVE-9554 should go into trunk and then this patch and be done on top
of it. I will have a patch there shortly.

> There are significant issues when Hive uses MSSQL as metastore backend to support unicode,
since MSSQL handles varchar and nvarchar datatypes differently. Hive 0.14 metastore mssql
script DDL was using varchar as datatype, which can't handle multi-bytes/unicode characters,
e.g., Chinese chars. This JIRA is going to track implementation of unicode support in that
case.
